PROBOLIC®-SR- 12-hour Sustained Release Bio-Efficient ProteinProbolic®-SR's patented 12-hour sustained release micro-feed technology and superior Critical Five Amino Acid Score (CFAAS) are major breakthroughs in protein supplementation. These two exclusive breakthroughs have set new standards in the bio-efficiency and anabolic effects of protein by giving you something no other protein can: a continual, 12-hour supply of the most critical amino acids to stimulate muscle growth, improve recovery and prevent catabolic muscle wasting.Amino acids are the building blocks for muscle tissue. In order to acheive maximum muscle growth, you must have an adequate supply of amino acids to feed your muscles. Certain amino acids are more important than others for stimulating and supporting muscle growth. These amino acids are called the Critical Five amino acids which include glutamine, arginine, and the BCAAs (leucine, isoleucine and valine). PROBOLIC-SR's engineered protein matrix of whey concentrate, soy isolate and casein is precisely formulated to supply the absolute highest levels these Critical Five amino acids. Aside from providing the highest Critical Five Amino Acid Score, the protein matrix also provides a fast, medium and slow "release profile" which improves bio-availability and nitrogen retention.The exclusive patented Sustained Release Micro-Feed technology further enhances the "release profile" and provides a continual supple of Critical Five amino acids for up to 12 hours. This controlled, sustained release of amino acids to your muscles increases bio-availability and nitrogen retention and creates the ideal anabolic/anti-catabolic state for maximum muscle growth and prevents muscle breakdown. PROBOLIC-SR's Micro-Feed technology makes it the most bio-efficient protein available.Feed your muscles with PROBOLIC®-SR -- the 12-hour muscle feeder!

For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Dose: Refer to label instructionsSome athletes believe rice protein may also improve blood flow to muscle to enhance growth and repair. However, no research has investigated the effects of rice protein on athletic performance.

Dose: Refer to label instructionsDieters who are gluten or dairy sensitive and looking to supplement protein might consider rice protein, though its actual benefits for weight loss have not been studied.(more)

Compared with other protein supplements, rice protein has more of the amino acid arginine, and since arginine is a vasodilator that can enhance blood flow to tissues, some athletes believe rice protein may also improve blood flow to muscle to enhance growth and repair. However, no research has investigated the effects of rice protein on athletic performance.

Dose: Refer to label instructionsDieters who are gluten or dairy sensitive and looking to supplement protein might consider rice protein, though its actual benefits for weight loss have not been studied.

Rice protein is extracted from rice and used in some protein supplements. Vegetarians may prefer it over protein supplements made from animal sources (such as whey or casein, which are milk proteins). Since rice is rarely involved in food allergies,1 rice protein may also be preferred by people with food allergies, and may be suitable to use in hypoallergenic infant formulas.2 Rice protein is not a complete protein, however, due to insufficient levels of the amino acids lysine and threonine.3, 4 Therefore, these amino acids are often added to rice protein products to correct this imbalance.

The best protein supplement I have tried. I take it twice a day in roughly 12 hour intervals. The granules seem smaller which makes it easier to mix. I get extremely tired of chocolate everything and the vanilla tastes great.

Amazing protein. Ive taken it for a month so far and am on my second tub of this stuff. I never really had any gains and felt like protein was a waste of time and didnt use it for two years before this. My roomate recomended this stuff and convinced me to try it. This stuff is great I kill myself at the gym till the point that I can barely move then I take this and imeadiatelly feel its effects. I cut my belly fat and lost 8 pounds in a week then over the past month have started gaining weight so far 6 pounds. I have tried a few other products as well some effective others not so. Even though its a good product its anoying to mix it and im getting tired of the vanilla flavor thats all the cons I can think of. The only reason I would change this would be out of boredom but have decided to stick by it for a while(as an after workout protein) and maybe find something else to take in the morning and before bed time like GNC AMP(Tastes horrible to me but effective, easy to mix), or Muscle or Monster Milk(Allways wanted to try this stuff).

I just add a scoop to my cereal when I'm sore, and it keeps me full longer, has enough leucine to avoid problems by other lower quality proteins if you know what I mean... Saw bad reviews for the flavor of the chocolate taste, and thats why I go with vanilla, if I want chocolate just add coco...
